When you search the Scriptures, trying to be right and to do right, the angels who attend your footsteps are rejoiced. Angels of heaven come in a marked manner to those who respond to the evidence of the truth and try to obey it. And if these angels are not always seen, you are to remember that they are present just the same, only your natural eyes are not strengthened to discern the light.... (TDG 160.4) MC VC
